摘要
汇总收集了国内已建城镇污水处理厂的大量资料,分析探讨了污水处理厂厂区占地面积、运行及建设费用与处理规模之间的关系,为今后污水处理厂的设计规划、工艺选择、建设费用分析等提供参考依据。研究表明污水处理厂厂区占地面积与处理规模可用函数表示,且具有较高的相关性。城镇污水处理厂所选用的工艺和处理规模对其运行成本有较大的影响,分别对大中小规模的污水处理厂在不同工艺下的运行成本进行分析,得出大规模污水处理厂的工艺选择对其运行成本影响不大;中规模污水处理厂易采用氧化沟工艺;小规模的污水处理厂适合采用SBR工艺。建设费用与污水处理规模有密切关系,由于建设费用受多种因素影响,又以江浙地区为例,对其建设费用与污水处理规模之间关系进行具体分析,对以上结论给予一定的补充。
Lots of information on urban wastewater treatment plants（WWTP） in China were collected and summarized.The relationship between scale,area,operating and construction costs of WWTP was discussed and analyzed.References are provided for the further design and planning,crafts selection,construction costs analysis of WWTPs.The study shows that area and scale of WWTP can be expressed as a function which has a high correlation.Scale and crafts selected have a great impact on operating costs of WWTP.It respectively analyzes operating costs of different crafts of small,moderate and large WWTPs.The conclusions are that the crafts in large WWTPs have a small impact on operating costs,moderate WWTPs appropriately use oxidation ditch craft,small WWTPs use SBR craft.The relationship between construction costs and scale of WWTPs is close.Because of various factors on construction costs,a case in Jiangsu and Zhejiang region was used to specificly analyze the relationship between construction costs and scale of WWTPs.
